Hello everyone, I have a TechnoTrend TT-TVStick CT2-4400v2 USB tuner, as described here: http://linuxtv.org/wiki/index.php/TechnoTrend_TT-TVStick_CT2-4400 According to the article, the device is supported since kernel 3.19 and indeed, if I use a 4.1 kernel, I can pick CONFIG_DVB_USB_DVBSKY and everything seems to work. Unfortunately (for me), I've been asked to make this driver work on an ancient 3.4 kernel. The linuxtv article mentions: "Drivers are included in kernel 3.17 (for version 1) and 3.19 (for version 2). They can be built with media_build for older kernels." ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This seems to imply that I can use the media_build framework to automatically (??) back-port a 3.19 driver to a 3.4 kernel? This sounds too good to be true... How far back can I go? http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers I find the instructions not very clear. I have cloned media_tree and media_build. And I have my 3.4 kernel source in a separate "my-linux-3.4" dir. How am I supposed to tell media_build: "hey, the latest drivers are in this "media_tree" dir, I'd like you to compile this one driver for the kernel in this "my-linux-3.4" dir" ? Note that media_build/linux has scripts which reference include/uapi which did not exist yet in 3.4 Anyway, my confusion level is at 11. I'd be very grateful if anyone here can clear some of it!
